In a transmitter there is a distributor and assembly bank into which a predetermined quantity of an input payload from a source is repeatedly written according to a first distributor permutation to create as many input vectors as there are electromagnetic propagation pathways. A staging bank exists into which each input vector available from the assembly bank are repeatedly written according to a second distributor permutation. A presentation bank exists into which each input vector available from the staging bank are repeatedly written according to a third distributor permutation. One or more encoders repeatedly encode input vectors from the presentation bank; there being as many encoders as electromagnetic propagation pathways, and each encoder makes available each encoded ordered series of output levels for communication over the pathways. The banks and encoders are in up to four timing domains. A corresponding receiver, decoder, and reception, staging and disassembly banks and a sink are at the end of the pathways.
